Hmmm... I recently bought a 5.3 with a wiped out cam lobe and it's showing some Brass in the cam bearings. Seems like they're all worn in the same spot too. So they might be ok?

I've seen a lot of pics of brassy cam bearings on Tech, and when I did my cam swap at 37K my front bearing was kind of funky looking. Swapped the cam in and it's been 23K so far with no problems. When I bought my 27k LQ9 I noticed that the first cam bearing in that is showing a lot of brass too...from what I've seen and read here, I don't believe that it's a problem.

yes its normal. You will find all the blocks have the same look in all the same places. Its from them line honing with the bearings in the journal.
